So if 2 people take 9 hours to paint the room and you want to know how long it will take if 3 people were painting first you will have to find the slope, or the rate of change, to do this you have to divide 9/2.
9/2= 4.5
So it take 4.5 hours for one person to paint the room.
Therefore if there where three people painting it would be 3 x 4.5= 13 hours and 30 minutes.
The time it would take to paint the room would increase.
Answer:
can be written in another equivalent expression as
that could represent the perimeter of the square.
Step-by-step explanation:
The perimeter of the square is:
As we know that Equivalent expressions termed as the expressions which are same, even though they may sound or look a little different
so another equivalent expression that could represent the perimeter of the square will be:
as
Therefore, can be written in another equivalent expression as
that could represent the perimeter of the square.
The data of brand C suggests that brand C has the fastest clean time because it has the least average time
<h3>How to determine the brand that suggest the fastest?</h3>
To do this, we simply calculate the average time of each brand.
From the complete question, we have:
Brand A: 20, 40, 60
Brand B: 30, 60, 90
Brand C: 15, 30, 45
The average is calculated using:
Average = Sum/Count
So, we have:
Brand A = (20 + 40 + 60)/3 = 40
Brand B = (30 + 60 + 90)/3 = 60
Brand C = (15 +30+ 45)/3 = 30
The least clean time is 30 (brand C).
Hence, the data of brand C suggests that brand C has the fastest clean time
